* update grammar mutator

* docs(custom_mutators): fix missing ':' (#1953)
* Fix broken LTO mode and response file support (#1948)
* Strip `-Wl,-no-undefined` during compilation (#1952)
Make the compiler wrapper stripping `-Wl,-no-undefined` in addition to `-Wl,--no-undefined`.
Both versions of the flag are accepted by clang and, therefore, used by building systems in the wild (e.g., samba will not build without this fix).
* Remove dead code in write_to_testcase (#1955)
The custom_mutators_count check in if case is duplicate with if condition.
The else case is custom_mutators_count == 0, neither custom_mutator_list iteration nor sent check needed.

* Always compile with -ldl when building for CODE_COVERAGE
When building with CODE_COVERAGE, the afl runtime contains code that
calls `dladdr` which requires -ldl. Under most circumstances, clang
already adds this (e.g. when building with pc-table), but there are some
circumstances where it isn't added automatically.
* Add visibility declaration to __afl_connected
When building with hidden visibility, the use of __AFL_LOOP inside such
code can cause linker errors due to __afl_connected being declared
"hidden".

The previous implementation of "@@ handling"
in afl-cmin differed greatly from how it was
handled in afl-fuzz and how the documentation presented it.
It used to require that the @@ be its own argument separated
by whitespace and could not be used in situations like "--file=@@".
This change standardizes it to just look for @@ to be *in* an argument
in the same manner that afl-cmin.bash does, so that it will have
the expected and documented behavior.
